Video Editor With Video Transcoding Via GPU

[Jun aka Pekto]

Just wondering if any video pros here have experience with video-editing apps that support transcoding via GPU.

Or is it done via Windows API's and across the board for any video editor?

I was curious about it and checked out some articles. I didn't realize transcoding via gpu has come a long way:

I heard about this but I had no idea. I even thought new softwares already utilizes gpu.

3d particle effects have been using the gpu for rendering the effects for awhile now. effects like those pixie dust, stars, comets that is on 3d rendering softwares or stand alone effect compositors. I guess it's same way how real time effects on games where created.

what I am aware of recently is the photoshop cs4 utilizes opengl and gpu's ram.

What surprised me was the GPU's superiority over quadcores, even the i7's. I wasn't expecting gpu transcoding to be that good.

If that's the case, then I won't miss having such a mighty quadcore since my main use for one would be in video editing. I guess I can sit pretty with my lowly triple core Phenom II and buy a video editing app that has gpu transcoding built-in.

I'm only speculating here, I think special effects and real 3d utilizes Gpu while the cpu still handle most of the encoding. but I read avivo video converter uses the gpu solely. perhaps it's really up to the software how to make use of the hardware indeed.

today, I just ordered HD 4850. hope it won't have encoding problems like my both AGP and PCI-E x1650 on effects software I use.

Wouldn't you know it......

As soon as I started inquiring/voicing concerns about gpu transcoding, ATI comes out with new (9.12) Catalyst drivers and Avivo Video Converter.

Installing now.....

What kind of effects software do you use? Me. I'm mainly home user level. Whatever came with Video Studio 11 or Sony Vegas is fine. Nothing cutting edge like Final Cut Pro or anything.....

I might buy Pinnacle's Studio HD. It's on sale right now.

Anyway, I've installed the latest Catalyst and Avivo Video Converter.

I'm converting a 2.5gb mpeg2 to a 285mb 720p H264 mp4. Transcode time is estimated at 34 minutes.

First, I'm not sure how the video would look since the stock footage resolution is 720x480. My guess is it'll look huge and squished. Second, I can't even remember if 34 minutes convert time is good or not. But, we'll see soon enough. This is just a test to see if it works on my rig.

CPU utilization is still in the 40% range. But, it's nothing like the 90-100% CPU usage with my other transcoder apps.

It just occurred to me that Windows Live Movie Maker supports ATI Stream and nVidia CUDA.

All this video clips have been piling up really fast.
